Hi Oliver,
Any docs you have on EDC, please send/share, especially on how to diagnose. I have read a lot of those already and most have key critical info missing. So you need to read all 10 and then aggregate. Pain in the butt and time consuming. That is basically what my doc is doing - aggregating all data from all BMW docs and all additional data found by users etc.
I have a list of error codes, but they are basic, like:
Valve fault, rear - Codes 80, 81, 82, 83, 84, 85
I note you had code 80 and some different text about the ground circuit. if you have any info on codes with more info on what they mean that would help a lot.
And of course once i have finished my doc, any input and feedback would be great. Hopefully later this week.
And FYI: My car was showing error 50 and 53 on the EDC and the EDC light comes on and stays on, but the shocks don't seem to change. I checked my wires to the front two shocks and i had a worn wire on the front left (drivers) shock. I will repair that tomorrow, reset codes and go for a drive and see how it works.
Quick update...i started stripping back the black exterior cover for the 3 wires to the shock. As i do this the yellow, red and white insulation on the 3 wrires inside is just crumbling and falling off. So now i have the shock wire with about 2" of bare wires and no insulation - i have not cut any of the wires. Using my variable DC power supply (

The other valve im not sure. Tomorrow i am going to try the same test with the right front shock and see if i can hear both valves triggering. If one is silent than ill assume the left shock is fine and then i will use "liquid tape" to seal the bare wires on the left shock and then clear codes and see what happens.
